To all whom it may concern:

'Be it known that we, JoHN B. lVns'r and LOUIS J. WALZ, both citizens ofthe United States of America, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Apparatus for Heading Rolls of Paper, of which thefollowing is a full, clear, and exact description.

In preparing a roll of newsprint paper for shipment, the customarypractice is to wrap the roll in heavy paper wide enough to extend beyondthe ends of the roll, and fold the overlapping edges of the wrapperinwardly and downwardly, after which a circular or disk-shaped head ofstiff paper or light card is affixed to the infolded wrapper by means ofglue or other suitable adhesive. In performing these operations thepractice has been to affix one of the heads and then up-end the roll sothat it stands on the headed end, after which the head is applied to theupper end of the roll and a heavy weight placed on top to hold the headin position until the glue or paste has set. Such rolls of paper arelong and unwieldy, and also heavy, and it will therefore be seen thatconsiderable labor is involved in the operations described, whichinvolves handling a roll as long as six feet in some cases and weighingupward of 1200 to 1400 pounds. In fact it requires several work men towrap and head a roll of paper properly, and moreover the work is slow aswell as heavy. r

We have accordingly been led to devise our present invention, which hasfor its object to provide simple and effective apparatus by which oneman can head a roll of paper with comparatively little labor and in muchless time than formerly was required in the operation. To this and otherends the invention consists in the novel features hereinafter described.

In carrying out our invention in the preferred manner we provide a pairofflat abutmen'ts' to receive lengthwise between them the roll of paperwhich is to be headed, the abutments being movable toward and from eachother to accommodate rolls of different lengths. 'Between the abutments,at the sides thereof, extend a pair of tensioning members which may bein the form of stout cables or chains, and associated with one of theabutments is a tensioning or binding member which is associated with thecables or chains in such manner that when the binding member is actuatedthe abutments will be drawn firmly against the ends of the roll.Preferably also the binding member mentioned is sov constructed andarranged that it will lock itself in the binding position therebyholding the abutments in position until the glue on the headers, whichare suspended on the inner faces of the abutlnents, has set. The bindingmember can then be released from locking position and the abutmentsremoved, leaving the roll perfectly wrapped and headed for handling orshipment.

The embodiment outlined above is illustrated in the accompanyingdrawing, in which Figure 1 is a side View showing awrapped roll of paperin position between the abutments before the latter are drawn up againstthe ends of the roll. Fig. 2 is a side view similar to Fig. 1 butshowing the tensioning member rocked or thrown to binding position, withthe heads pressed firmly against the infolded ends of the wrapper.

Fig. 3 is a plan view of Fig 2.

F ig, 4 is an end view from the left of Fig. 2.

Fig. 5 is a detail perspective view of one end of a headed roll ofpaper, with the head partly broken away to show the infolded edge of thewrapper.

For the sake of lightness and convenience in handling, the abutments l0,11 are preferably made of wood as indicated in Fig. 4, strengthened, byvertical battens 12, 13, which are provided at their lower ends withfeet 14, 15. These feet, which are turned outwardly to avoid possibilityof damage to the roll of paper, may be made of short pieces of angleiron or pieces of bar iron bent to the proper shape. Across one of theabutments, as 11, is a bar 16, the ends of which extend beyond the sidesof the abutment and are equipped with open hooks 17 to engage thetension members 18 which, as shown, may be in the form of chains, theterminal links of which fit over the hooks mentioned.

The battens 12 and 13 on the other abutment, 10, are provided withoutwardly extending brackets 19 which are alined transversely, that is,their fiat upper surfaces are in the same horizontal plane, to receivethe self-locking bar 20, which serves to put the chains under tensionand draw the abutments toward each other. This bar 20 is flat in form,and when in the position shown in Fig. 1 it is supported on the bracketsby its lower edge. The ends of the bar, which overhang the sides of theabutment, are provided with fingers 21, adapted to engage one or anotherof the links of the adjacent chain, according to the length of the rollbetween the abutments, as will be readily understood. As indicated inFig. 1, these fingers are above the lower edge of the bar, preferably atthe upper edge thereof.

At the center of the upper portion of each abutment is a stud 22 onwhich the heads, as 23, well coated near their edges with glue, paste,or other suitable adhesive, are hung. It is to be understood that thesestuds we tend inwardly, but little if any farther than is necessary tohold the heads in position, so as not to damage the roll of paper whenthe binding pressure is applied.

The roll having been wrapped and the edges of the wrapper foldedinwardly, as

indicated at 24: in Fig.5, the abutments,

with the paste-coated heads in place, are arranged at the ends of theroll as indicated in Fig. 1, and the chains are hooked over the fingers21. A forked handle or lever 25 is then set down over the fiat bar 20and is rocked outwardly and downwardly, thereby swinging the bar 20 downfiat upon the brackets 19. As will be readily understood, this movementof the bar 20 draws the abutments toward each other, and thereby bringsthe heads 23 firmly upon the infolded edges of the wrapper. The brackets19 and the hooks 17 being at the same or substantially the same height,it will also be seen that the rocking movement of the bar 20 brings thesame into the plane of the chains, so that their tension exerts notendency to swing the bar out of its locking position. In short, the barin effect locks itself. As soon as the glue or paste or other adhesiveon the heads has set, which usually occupies but a short time, the lever25 is again applied to the binding bar 20 and the same is raised to theposition of Fig. 1 by swinging the lever upwardly and inwardly. Thechains can then be released at either end andthe abutments removed,leaving the heads attached to the wrapper, as indicated in Fig. 5.

Itwill be observed that during the above operations the roll does nothave to be upended, and that if it has to be moved at all,

the necessary shifting can be effected by rolling it on the floor, whichrequires comparatively little effort. Also, the handling of the chainsand abutments is not diificult and their arrangement in the properpositions can be effected rapidly and easily by one workman.

Metal wear-plates 26 may be provided on the battens just above thebrackets 19 to protect the battens against wear which would be caused bythe rocking movement of the bar 20.

The apparatus is not only simple and effective in use, but is also freefrom complication and can be constructed at comparatively small cost. Atthe same time it can be made strong enough to withstand use for anindefinite period.

It is to be understood that the invention is not limited to the specificdetails herein described and illustrated, but can be embodied in otherforms without departure from its spirit.
